In a region of constant potential

A

the electric field is uniform

B

the electric field field is zero

C

there can be no charge inside the region

D

the electric field shall necessarily change if a charge is placed outside the region

Text Solution

Verified by Experts

The correct Answer is:
B, C
`E = -(dV)/(dr)`
If V is constant, then E = 0
Again, `oint_(S) vec(E ) cdot dvec(S) = q/(epsilon_0)`
Since , E = 0.
So, q = 0.
